Answer 2

Step-by-step explanation:

99x+101y-499......(1)

101x+99y-501......(2)

y=501-101x/99

by substituting the value of y in equation 1

99x+101{501-101x}/99

99x+50601-10201×/99

9801x+50601-10201x=99

9801x-10201x=99-50601

400x=50502

x=50502/400

x=126.255

then,on substituting the value of x in equation 2

101(126.255)+99y-501

12751.755+99y-501

12751.755-501=99y

12250.755=99y

y=12250.755/99

y=123.745
